摘要： A shift assist projection is provided on a large bicycle sprocket to assist in shifting a chain to the sprocket from an adjacent smaller sprocket. The shift assist projection extends axially from one side of the sprocket. The shift assist projection has an axially facing chain catching surface that faces the center plane and the teeth of the large sprocket to engage an outer link plate of the chain. The chain catching surface is preferably angled a varying amount relative to the center plane of the large sprocket. The chain catching surface preferably has a rearward most rotational edge that is located closer to the center plane than a forward most rotational edge as viewed substantially along a moving direction of the chain when the chain is being shifted from the smaller sprocket to the large sprocket.
摘要翻译：在大型自行车链轮上设置换档辅助突起，以帮助从相邻的较小链轮将链条移动到链轮。换档辅助突起从链轮的一侧轴向延伸。换挡辅助突起具有面向中心平面的轴向面向的链条捕捉表面和大链轮的齿以与链条的外链板接合。链条捕捉表面优选地相对于大链轮的中心平面具有不同的量。当链条从较小的链轮移动到大的链轮时，链条捕获表面优选地具有最靠后的最大旋转边缘，该后端大致沿着链条的移动方向观察到比最前面的旋转边缘更靠近中心平面。

摘要： An assisting apparatus for using power from a rotating member to assist the operation of a bicycle transmission includes a mounting unit; an input transmission member coupled to the mounting unit, wherein the input transmission member moves to at least a neutral position, to an upshift position and to a downshift position; and an output transmission member coupled to the mounting unit, wherein the output transmission member moves to at least a first output position and a second output position. A rotating member engaging member moves between a rotating member engaging position and a rotating member disengaging position, and a motion transmitting mechanism transmits motion from the rotating member engaging member to the output transmission member. A switching mechanism moves the rotating member engaging member to the rotating member engaging position when the input transmission member is in at least one of the upshift position and the downshift position.

摘要： A crankset is provided that is mounted on a crank spindle rotatably mounted in a hanger component of a bicycle and that meshes with a chain. The crankset includes a plurality of sprockets, a crank component, and a chain guard. The plurality of sprockets are lined up in the axial direction so that the number of teeth increases outward in the axial direction. The crank component has a plurality of arm portions extending radially for fixing the plurality of sprockets. The chain guard is provided substantially in ring form on the inner side, the side disposed toward the hanger component, of the small-diameter sprocket with the fewest teeth of the plurality of sprockets such that the gap between the hanger component and the inner side is smaller than the size of the chain.

摘要： A bicycle hydraulic brake actuation device includes a hydraulic master cylinder housing having a bore, a lever, a master piston and an adjuster. The lever is pivotally coupled to the hydraulic master cylinder housing for movement between an at rest position and a brake engagement position. The master piston is disposed within the bore and having an adjustment end. The adjuster is operably disposed between the adjustment end of the master piston and a portion of the lever. The adjuster is movable between a plurality of adjustment positions relative to the adjustment end such that with the lever in the at rest position, movement of the adjuster between the plurality of adjustment positions moves the master piston between a corresponding plurality of adjustment positions along an axial length of the bore.
